In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

Embodiment one

As shown in Figure 1, an adjustable power cabinet shock-absorbing base includes a power cabinet body 1 and a base 2, and the base 2 is provided with a first straight pipe 3, a stepped hole 4, a first tapered pipe 8, a thin Pipe 9, second tapered pipe 10, second straight pipe 11, the step hole 4 communicates with the outside world upwards, the first straight pipe 3 is slidably connected with the first piston 7, and the step hole 4 is slidably connected There is a slide plate 5, the lower end of the slide plate 5 is welded with a push rod 6, the lower end of the push rod 6 is against the first piston 7, the second straight pipe 11 is slidably connected with a second piston 12, and the second straight pipe 11 is slidably connected with the second piston 12.

In the adjustable power cabinet shock-absorbing base of the embodiment of the present invention, the power cabinet body moves up and down when it is shaken, and the installation plate moves up and down together with the power cabinet body. Since both the first spring and the second spring are in contact with the installation board, and the first spring The end of the second spring away from the mounting plate is fixed, so when the mounting plate moves up and down due to the vibration of the power cabinet body, the first spring and the second spring can offset the vibration and prevent the components in the power cabinet body from being damaged by shock;

When the environment where the power cabinet body is located frequently causes vibrations with a small vibration amplitude and a high vibration frequency, turn the operating handle to drive the threaded rod to rotate. Since the threaded rod is threadedly connected with the baffle, the threaded rod will move upwards, and the power cabinet body will go down at this time. Press the first spring to make the slide plate, ejector rod, and the first piston slide downward. Since each pipeline is filled with hydraulic oil, the second piston will slide upward. At this time, the mounting plate moves downward, and the compression of the second spring decreases. The elastic force of the second spring on the mounting plate is also reduced;

The pressure on the first spring is equal to the sum of the elastic force of the second spring plus the gravity of the mounting plate, so the pressure on the first spring decreases, and the compression of the first spring also decreases; in summary, the two The amount of compression of the springs is reduced. At this time, the pressure that causes the two springs to produce a certain amount of elastic deformation is less than the pressure required for the initial state. At this time, when subjected to vibrations with high vibration frequency, the first spring and the second spring can ensure The vibration is rarely transmitted to the main body of the power cabinet, thereby reducing the damage of components in the main body of the power cabinet due to vibration;

When the environment where the power cabinet body is located frequently causes vibrations with large vibration amplitude and low vibration frequency, reversely rotate the operating handle to make the second piston slide down. Since the pipeline is filled with hydraulic oil, the first piston will slide upward under force. , the slide plate slides upward synchronously to compress the first spring, and because the pressure on the first spring is equal to the sum of the elastic force of the second spring plus the gravity of the mounting plate, when the first spring is compressed, the second spring will also be compressed at the same time, In this state, the pressure that makes the two springs produce a certain amount of elastic deformation is greater than the pressure required in the initial state. At this time, when the vibration frequency is low and the vibration amplitude is large, the first spring and the second spring only need to be small. The deformation can offset the vibration, thereby greatly reducing the transmission of vibration to the power cabinet body, thereby reducing the damage of components in the power cabinet body due to vibration;
